In its third version, Doshi Audio Evolution tube mastodons offer as much as 160 watts per channel – all thanks to the use of 12SJ7GT, 12SN7GT and KT150 tubes. The signal-to–noise ratio reaches 80 dB, the work is carried out in the band from 10 to 80,000 Hz - if you need an AB-class device that provides lamp warmth and, at the same time, is able to cope with any speakers, the choice is obvious.
